Application filed Hovember 14, 1912. Serial No. 731,402.

To all whom it may concern Be it known that I, WILLIAM H. BAN- zn'r'r, a citizen of the United States, and a resident of Bergenfield, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Machines for Makin Window- Envelo Blanks, of which the ollowing is a speci cation.

This invention relates to machines for making window envelop blanks with a display opening therethrough provided with a transparent covering.

The object of'm improvements is to provide means for orming the opening, for applying a patch of transparent paper thereover, for aflixing that patch against the borders of the window opening in a continuous web of paper, severing that web into successive envelop blanks in proper relation to the window openings therein, all duiging the continuous advancement of the we The machine of this application is adapted for producing envelop blanks in accordance with the subject matter of my copending application for Letters Patent of the United States for improvements in the process of making window envelop blanks, Ser. No. 719380, filed. September 9, 1912, and to which reference may be had.

With these ends in view I employ mechanism illustrated in its preferred embodiment in the drawings accompanying this specification wherein p Figure 1 is a diagrammatic sectional elevation of my improved machine. Fig. 2 is a plan view of the patch cutting and feeding mechanism. Fig. 3 is an enlarged plan view of a portion of a continuous web of paper and of an envelop blank severed therefrom, illustrating the several steps in the production of envelop blanks by my improved machine. Fig. 4 is a diagrannnatic side elevation corresponding with Fig. 1 and showing the gearing for driving the several rotative parts-of my machine. Fig. 5 is a detail side elevation showing the cutter mechanism for'the transparent strip. Fig.v

6 is a detail enlarged View. of the window cutting mechanism. Fig. 7 is an enlarged view of a further detail. Fig. '8 is an elevation of cutting roll 23 viewed from the right hand side of Fig. 1, and to a larger scale than that of Fig. 1.

My improved machine comprises a pair of feed rolls 5, 6 by which the continuous web of paper 4 is led fromthe usual roll 2 mounted on shaft 3. From rolls 5, 6 said web 4 is passed upwardly over roll 7 and thence to and between rolls 8, 9. Said roll 8 is provided with opposite cutters 28, havmg suitable profiles for cutting window openlngs 10 (Fig. 3) in the-web, and said cutters are skewed on said roll to' position their cuts respectively, as illustrated in said Fig. 3. Roll 9 is preferably a hardened roll for coaction with the cutters on roll 8.

Cutter 28 is provided with barbed spear 30 which, as said cutter coacts with roll 9, punctures the web, and as rolls 8, 9. continue their rotation conducts the window blank away from the web. Said window blank may be removed from spear 30 by means of ejector 32 actuated by fixed cam 33. Ad-

jacent and to the left of rolls 8, 9, Fig. 1,

gummed portion 13, Fig. 3. Said gum roll 7 may be supplied with gum in the usual manner from gum supply 14: of well known character.

To the left of roll 11, Fig. 1, is a roll of transparent paper 15 and adjacent to said roll is a pair of feed rolls 16 and upper and lower cutting knives 17 18 respectively. Between said cutting knives and roll 11 are upper and lower patch feed rolls 19, 20 re-' spectively. Said roll 20 preferably has its axis in the same horizontal plane as and parallel with the axis of roll 11 and is situated for coaction therewith to feed the web of paper downwardly as illustrated. Said roll 20 is provided with opposite patch cli s 21, 22 for gripping the patches successive y delivered thereto. Said clips may be urged to their work by springs as 35 to clip 21 and may be lifted by the engagement of their rolls as 37 of said clip 21 with fixed cam 36.

The roll of patch paper 15, feed rolls 16 and cutters 17, 18 are in skewed position relatively to rolls 19, 20, see Fig. 2, so that the successive patches are delivered to roll 20 skewed relatively thereto and in correspondence with the skewed position of windows 10 in web 4. Patch web feed rolls 16 may be geared together by gears as 38 and may be driven from shaft 43 of 'roll 19 by.

' 'tached to the arm of cutter 17.

Below roll 20 is cutting roll 23 for coac- I tion with hardened roll-24 below roll 11 for severing the web into envelo blanks, the sides of each of which prefera ly formsubstantially a parallelogram having sides parallel with the sides of the web, as illustrated in Fig. 3, and for cutting notches 25, 25 in the edges of the web respectively in suitable relation to the envelop blank. Said roll 23 is of such a diameter and the cutting members are so disposed relatively thereto as to sever two blanks at each revolution.

Below rolls 23, 24 is receiving box 31 of some convenient construction for receiving the completed blanks as 27, Fig. 3.

For the present purpose shaft 51 may be considered the driving shaft of the machine and fixed thereto is gear 61 which drives gear 52 on shaft 90 of roll 9; on shaft 80 of roll 8 is fixed gear 53 which meshes with and is driven by gear 52. Gear 55 fixed to shaft 7 0 is driven from gear 52'through intermediate 54. Gears 58, 59 are fixed to shafts 50, 60 respectively and said gear 58 may be driven from gear 54 through intermediates 56, 57.

Returning to main gear 61, said gear drives gear 62 fixed to shaft 41 and said gear 62 drives gear 63 fixed to shaft 42; gear 64 fixed to shaft 43 is driven by gear 63; fixed to shaft 40 is gear 65 driven by gear 62 and gear 66 ofp asting mechanism 14 is driven by gear 65 and in turn drives gear 67 of said pasting mechanism. Gear 69 fixed to shaft 45 is driven from gear 61 through intermediates 71 and 72 and gear 68 fixed to shaft 44 is driven by gear 69.

While I have herein illustrated the transparent patch paper as fed from a continuous web and cut into portions as needed foruse I do not Wish to limit myself to the illustrated details of that mechanism as various modifications thereof may be had by those skilled in the art without departing from the spirit and scope of my improvements.

The practice of myimproved process is as follows: Web 4 being fed in the direction of its arrow over roll 7 and between rolls 8, 9, the window opening 10 is cut therein by cutting roll 8 in coaction with lower roll 9 and the perforated web is fed forwardly over roll 11, whereupon gummer 12 deposits onto the upper face of said web, gum' 13 naoaeao about said window opening 10. During these several steps rolls 16, 16 have fed forwardly over knife 18 a suitable length of transparent patch paper 26 and thereupon clip 21 grips the leading end of said patch strap and simultaneously knife 17 descends an severs the patch length from the web. Roll 20 in its continued rotation then delivers said patch portion against the gummed window border of the web and as said web and patch pass between rolls 11, 20 the patch is squeezed down onto the web and by means of the gum, affixed thereto. The downwardly moving web then passes between cutting roll 23 and plain roll 24 whereby the envelop blank profile is cut and the completed blank 27 is delivered into hopper. 31.

It will be understood that my improved machine is a continuously operating one, the several rotary members being maintained in constant rotation, whereby a product greatly increased over that to be had in intermittently operating machines may be had.
